IMPROVEMENT IN THE MANUFACTURE OF FUNNELS.

Specification forming part of Letters Patent No. 139,873, dated June 17, 1873 application filed January 18, 1873.

To all whom it may concern:

Beit known that I, LEVI R. Consrocx, of Baltimore, in the county of Baltimore and State of Maryland, have invented a new and valuable Improvement in the Manufacture of Funnels; and I do hereby declare that thefollowing is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings, making a part of this specification, and to the letters andfigures of reference marked thereon.

Figure 1 of the drawings is arepresentation of a plan view of the blank. Fig. 2 is a view of my nozzle complete.

This invention has relation to the construction of nozzles for funnels having outlets or tubes for the escapeof air; and it consists in forming the tube or channel portion of one piece with the metal of the nozzle, upon the perforated portion of which it is afterward turned when the nozzle is struck into shape.

The object of this invention is to render the expense of manufacturing the class offunnels referred to above so small that they may be brought into general use, competing successfully with the common plain funnel.

In the accompanying drawings, theletterA indicates the body of the nozzle. In striking out this blank, it is extended at the side next the perforations, b and upward,,forming the channel-piece B in the same piece of metal with the main portion or body of the nozzle. A small notch is made at e, between the channel-piece and the upper edge of the body A. The channel-piece is so arranged with reference to the perforated portion of the nozzle that when it is reflected or folded back upon the metal of the nozzle, it willcover the perforations. The edge of the channel-piece should then be soldered to the inner wall of the nozzle, making the air-tube complete,'so

far as the nozzle portion is concerned.

When the nozzle is turned into shape, as shown I I in Fig. 2 of the drawings, it maybe secured by soldering the edge of the blank to the exte-- What I claim as my invention, and desire to secureby Letters Patent, is-

The perforated nozzle-blan k for funnels, provided with the extension B in the same piece.

of metal to cover in the air-channel, as specified.

In testimony that I claim the above, I have hereunto subscribed my name in the presence of two witnesses.
